Looks reasonable, but I wonder if we should just go ahead and add
adreno_is_a640_family() in a similar vein to
adreno_is_a650_familiy()/adreno_is_a660_family().. I think most of the
'if (a640) ...' should also apply to a680?

Until we move to features flags (and if needed, other config table
params.. I know UMD needs more than just booleans but that may not be
the case on kernel side), I'd kinda prefer "_family()" to make it
clear that it applies to more than just a single gpu but a
sub-generation of a6xx.. I'd kinda assume the differences in memory
configuration (iirc dual vs quad ddr interfaces) have some small
differences between a640 and a680 that matters somewhere on the kernel
side?
